What this medicine is used for

Betahistine is used to treat Meniere's Syndrome, a disorder of the inner ear.

ringing in the ears (tinnitus)
loss of clear hearing
problems with balance (vertigo)
These symptoms may also be associated with nausea, vomiting and headache.

How it works

Betahistine works by improving the blood flow of the inner ear and restoring it to normal. It also acts on the nerve endings in the inner ear to normalise the way in which the nerves respond to outside influences.

Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
